The business owners didn't want to wait for the city to install a public restroom, so they did it themselves.
As an old-time photo maker, Joanna Urrago often dresses up like a pioneer woman, but that doesn't mean she wants to live like one.
"I imagine it smells a lot like what in the inside of the vestibules in ancient Rome smelled like," she said last month.
Urrago has tried to stop the bathroom breaks near her business by taking photos of the culprits and adding surveillance cameras, but nothing has deterred them.
In a last-ditch effort to solve the problem, Urrago decided to build her own outhouses and set them up in Occidental Park.
The city already has plans to install what's called a Portland Loo in the area, but Urrago said it will be located too far from the park where homeless people gather.
Many people in the area on Thursday welcomed the newest addition to Pioneer Square.
"I don't know if you caught the wind coming down here, but there's been a movement in the city to provide more public restrooms," a tour guide said.
In 2006 the city spent more than $1 million on state-of-the art public bathroom in the area. After reports surfaced of drug using, drug dealing and sex acts in the bathrooms, the city ditched the toilets.
Urrago installed her homemade porta-potties in front of police officers and a Parks and Recreation worker, but the officers decided to wait on word from higher-ups before making a decision about removing the toilets.
Urrago said she's going to keep the outhouses in place until she's told to take them away.
"Sanitation should be public priority number one," she said.
The outhouses fall under the Seattle Department of Transportation's jurisdiction.
